西門子3RW3全系列軟啟動(dòng)器可以限制起動(dòng)電流和起動(dòng)轉(zhuǎn)矩，有效防止機(jī)械沖擊以及電網(wǎng)電壓降。通過相位控制降低電機(jī)電壓，并能夠在可調(diào)起動(dòng)時(shí)間內(nèi)將電機(jī)電壓增加到電網(wǎng)電壓。軟起動(dòng)和軟停車可以保證連接設(shè)備上的應(yīng)力最小化，確保生產(chǎn)運(yùn)營(yíng)平穩(wěn)。采用兩相控制的SIRIUS 3RW30/屬于標(biāo)準(zhǔn)型，最適用于功率最大55KW的標(biāo)準(zhǔn)應(yīng)用。3RW40也屬于標(biāo)準(zhǔn)型，適用范圍為75～250KW，3RW44屬于高性能型產(chǎn)品，適用范圍為15～1200KW。3RW40、3RW44都是西門子公司的新產(chǎn)品。 應(yīng)用： 通風(fēng)、泵、傳送、壓縮機(jī)、風(fēng)機(jī)、混合機(jī)、銑床、碎石機(jī)。 　 西門子軟啟動(dòng)器3RW3全系列 3RW2122-1BG01 3RW4422-1BC44 3RW4443-6BC44 3RW2124-1BG01 3RW4422-1BC34 3RW4443-6BC34 3RW2125-1BG01 3RW4422-3BC44
